" TYPE-WRITING mourns.

To all wkomc'tn'oncern Be it knownfth at -I, AnoLPHUs S. DENNIS, a citizen ofgthe United States, residing in Lakewood, in thecounty of Cuyahoga and State 'of- Ohio," have invented .certain new and-useful Improvements in Type-Writing f which they following is'a specification.-.--

I 1 v -This invention relates to. means for superposing and feeding the work-sheets in typewriting machines.

One ofthe main objects. of the invention is, to provide improved means for con- 'veniently and accurately placing one sheet over another or othersin any desired relationship; the invention being particularly useful in cases where the leading edges of the superposedwo-rk-sheets occupy different positions during the writing operation, in-

stead of coinciding. in the usual manner.

This invention makes provision for placing sheets in' the 'machine so that the first line of writing lwillfallin diflerent positions on different sheets. In order to attain this result, a special work-sheet supporting-board or table is arranged at the introductoryside of the typewriter platen, and

it'is provided with a scale of numbers which agrees'with a similar scale or column of numbers on the margin of the rear side of the work-sheet; the relation being such that when the Work-sheet is inserted with its leadin-g'edge against a gage, the numbers on the back of the work-sheet will register with the numbers on the sheet-board. Thus it will be seen :thatthe sheet-board is as serviceable'for the purposes of this invention, as if it were itself a work-sheet permanently and properly fixed in the machine. I

The invention is shown in connection with a revoluble platen in an Underwood fronts trike writing machine, and as usual, the worksheet, when introduced into the machine, is upside-down, and its rear side faces the operator. Therefore, the numbers on the work-sheet read from the bottom to the top of the rear side of the sheet.

The principaljobj'ect of the numbering on v the sheet and'.on'the board is to enable the operator "to place" several sheets in the machine, one of the'msubstantially in advance Specification of Letters Patent.

of another, and allithe sheets accurately positioned with reference to one another, so

that the first line of writingwill fall at dlfferent desired points on the different.

sheets. The operator first inserts a sheet with its leading edge against a gage. He

bers will register with those on'the feed 7 the first line of writing on the first ini I board; and if the operator should desire serted sheet to fall ten line-spaces below the first line,.of writing on the second in-- serted sheet, he will, before inserting said second sheet, advance the first sheet ten linespaces, which he can readily do by reference to the scale on the sheet board, and he may also advance both the first and second sheet. number of spaces before. inserting a 'third sheet, and so on, the interleaving carbon sheets being inserted as necessary.

For convenience, the faces or fronts of the work-sheets are provided with numbered lines which agree with the line-spacing movements of the platen, so that the first line of writing will be numbered for con-' venience 2, the second line 4, the third and so on and the spacing or interval between the'successive lines-on the line face of the work-sheet are equal to those on the rear of the worksheet; but the numbers in the margin on the face of the work-sheet read from top to bottom in the natural manner,

"From the foregoing, it will be understood that if the operator desires, for instance, the first typewriting to fall on line 18 of the first inserted sheet, andto fall on line 8 I will proceed by placingjthefirst sheet inthe Patented Apr. 18, 1916; 4 Application filed July 22, 1913.

machine and gaging it, and then a dvancing it by means of the feed rolls .ten points,

that is, until the number 1 8 on-the'rear of the first sheet registers with the-number 8 on the feedfboard which, it will be remembered, is equivalent to a work sheet permanently fixed in the machine.

When the operator places the second. sheet in the machine, its line 8 will register with. line 8 of the machine board, and hence with line 18 on the inserted sheet. The operator then inserts a carbon between the sheets, and turns the platen until line 8 on the front of the second inserted sheet reaches the printing position. The operator then writes on line 8, and the carbon copy thereof ap airs on line 18 of the first inserted sl :et, which may answer to the record sheet, in such work as condensed billing, etc.

The improvements further relate to the feed roll mechanism. Preferably in addin to the usual bottom feed rolls of the ,nderwood machine, there is provided a pc ,ial roll at the introductory side of the platen; and below this special roll is the gage for the leading edge of the sheet. The special roll may be released independently of the main or bottom rolls, and simultaneously the sheet gage may be thrown against the platen. Upon releasing the gage, the special roll is thrown against the platen and feeds a sheet to the bite of the platen and the usual main or bottom feed rolls.

The special feed roll referred to is suitably connected by gearing to the platen so as to positively drive the paper forwardly; and the same is true of the bottom rolls; the bottom forivard roll being connected to the bottom rear roll by a conveyor belt, whereby the accuracy of alinement of sheets secured by the use of said leading edge gage preserved as the sheets feed forwardly around the platen.

Another feature of the invention resides in the improved spring construction for pressing th e bottom feed rolls against the platen. These feed rolls are carried upon arms which radiate from a common shaft or support; and these arms have extensions which are engageable by arock shaft having cams to force the extensions upwardly, and thereby drop the arms and rolls away from the platen. These extensions are, according to the present invention, connected by means of a C spring which encircles said releasing shaft and seats in notches in said extensions. The pressure of the spring in each case is divided evenly between the roll arms. This gives a simple and inexpensive construction in which the tension of each spring is properly distributed between the forward and rear rolls.

()ther features and advantages will hereinafter appear.

Tn the accompanying drawings, Figure l is a perspective front view of the'platen frame of an Underwood front-strike writing machine provided with my improvements; some parts being broken away to disclose others. Figs. 2 to 6 are sectional side elevaaae aao tions to illustrate successive steps in operating the machine. Fig. 2 shows normal position. This figure illustrates how a sheet may be introduced as in ordinary correspondence, by adjusting it to the bite of the platen and the special feed roll. This adjustment may be preparatory to subse quently gaging the sheet as in Fig. 3 in which the special feed roll is shown released, and the leading edge of the sheet is shown resting upon the gage. Fig. 4 shows the same sheet advanced preparatory to the in sertion of a second sheet. Fig. 5 shows a second sheet inserted and gaged; a carbon being placed between the two sheets. Fig. 6 shows all three sheets advanced from the Fig. 5 position to position for writing the first line; it being noted that the leading edge of the first inserted sheet, which is next to the platen, is far in advance of the leading edge of the second inserted sheet, which lies outside of the first. Fig. 7 is a'sectional side elevation to illustrate the gear driving connection between the platen and the system of feed rolls. Fig. 8 is a diagrammatic perspective to illustrate the use of numbers insuperposing the sheets. Fig. 9 shows the superposed sheets brought to position for writing the first line. Figs. 8 and 9 correspond with Figs. 5 and 6. Fig. 10 is a fragment of the margin of a work sheet. showing the numbers running from bottom to top on the rear side thereof; the corresponding numbers on the front of the sheet showing in dotted lines.

by means of hand wheels 54. or the usual line-spacing mechanism 55. Rear. rolls 5G and front rolls 57 usually run upon the bottom of the platen to feed the work sheets around the same.

I provide a special sheet-supporting board 58 which extends upwardly and rearwardl} from the top of the paper shelf 53, and which may have opposite side gages 59 between which the work sheets fit. The face of this sheet board may be divided by horizontal lines 60 into spaces, and the spaces may be numbered as at 61, at the side margin of the board, the numbers reading from the bottom to thetop of the column. Each of the intervals between the lines 60 is equal to two line-space intervals, and for convenience the spaces are numbered only with even As seen at Fig. 10, the rear side of the work-sheet 62 has a corresponding column of numbers 63, reading from bottom to top, and agreeing with those at 61 on the sheet board.
